Question

Copilot forgetting topics and memories after recent update

Shea 0

Microsoft Copilot did an update last week and now it doesn't remember the two projects we had been working on for about a year. It also takes a long time for the page to load now and it crashes frequently, like a couple minutes after being on the page. I do have the free version of Copilot and have contacted Support and tested Copilot on multiple browsers and devices. It has the same issue on all of them.

Hi, Shea

Sorry for this frustration. Those tests make another browser reset less useful, but they don’t confirm whether the saved conversations are gone.

Here are some suggestions you can try:

First, preserve the saved record. In your Microsoft account’s privacy dashboard, go to Privacy > Empower your productivity > Copilot > Your Copilot app activity history > Copilot apps, then select Export all activity history. Open the downloaded file and check for the two projects. If needed, also check the separate Copilot Chat export under Copilot in Microsoft 365 apps.

Next, try a new conversation with a short, manually checked summary of one project’s goals, decisions, and next steps. Treat this as a temporary workaround, not a recovery of the original memories. Note whether that fresh conversation also crashes.

Add those findings to your existing support case, particularly whether the export contains the missing work. Avoid deleting history while investigating. I couldn’t verify a confirmed fix for the cross-device crashes.

Hi, Shea

It has been a while and I am writing to see how things are going with this issue.

Have you had a chance to check the replies provided?

Any update would be appreciated.

Sorry for the delayed response. I just tested your solution and it unfortunately did not help. The Copilot activity history didn't have any data in it when I exported it and I couldn't get the chat history to export at all. I did just check again and Copilot still does not remember what we had been working on. To be honest, I did not have my two projects saved as "projects" in Copilot before it updated as I didn't know that was an option. I had just been working with Copilot in the normal chat history, using what it remembered from our previous conversations.

Hi, Shea

Thanks for clarifying, and I’m sorry the export didn’t help. You were relying on ordinary chat history, so the earlier Projects advice wasn’t relevant.

One specific setting is worth checking: open… Settings and more > Chat settings > Personalization and make sure Chat history is enabled. This controls whether Copilot uses previous conversations to personalize replies. If it’s already on, leave it on rather than toggling it off as a reset.

If the original conversations still appear in the Chats list, open one directly and continue there instead of asking a new chat to remember it. You can revisit and continue saved conversations, although cross-chat recall does not retain every detail.

If those conversations are missing too, I recommend asking support to investigate missing ordinary chat history and failed exports, rather than missing Projects. Include the empty export and export failure in your existing case. I can’t confirm that the data is deleted or promise that support can restore it.

Thank you so much for your advice. Unfortunately, I've already tried your suggestions a few times in the past and it didn't work either. Whenever I try to open a previous chat, it either fails to load or causes Copilot to crash. On the rare occasion the previous chat has opened, Copilot has told me that the chat limit has been reached, to start a new topic, and will not allow me to continue where we left off. At this point, I've pretty much accepted that I will have to start over and have started creating notebooks for the two projects Copilot and I were working on. Luckily, I had saved some documents relating to the two projects and can upload them to Copilot. It's just odd, and inconvenient, that an update to Copilot would cause this to happen, especially since one of the projects is something I was completing for school.
